Abstract (en)
[origin: JPS6231294A] PURPOSE:To enable an overwriting recording and improve a recording efficiency by recording a signal of the same channel of two channel component signals on adjacent tracks on a tape pattern. CONSTITUTION:In the present invention, as an example, a luminance signal and a time base compressed multiple chrominnace signal form a two channel component signal. In a recording track pattern (part) recorded on a magnetic tape 23, an arrow 24 indicates a scanning direction of video heads A1, A2, B1, B2, and an arrow 29 indicates a scanning direction of the magnetic tape 23. Recording tracks 101, 105 are recording tracks recorded by the video head A1 and recording tracks 102, 106 are recording tracks recorded by the video head A2. Herein, a luminance signal (Y) Is adjacent to the luminance signal (Y) and a chrominance signal (C) is adjacent to the chrominance signal (C). Therefore, even when an overwriting recording (solid writing recording) is carried out, a level of an interference fromm an adjacent track is reduced and a high density recording having no guard band by the overwriting recording (solid writing recording) can be executed.
